School children with systolic blood pressure in the upper quintile had significantly greater body size-corrected left ventricular wall mass compared to those in lower blood pressure quintiles.
Observational (n=264)
From echocardiography measurements of left heart dimensions, cardiac output was estimated in 264 school children whose systolic blood pressure persisted in the lowest, middle, or highest quintile of the distribution for their age and sex. Children with blood pressure in the upper quintile were taller, heavier, and more obese. Echocardiographically determined left ventricular wall mass, corrected for body size, was significantly greater in these children than those in the lower quintiles of blood pressure. These children displayed a continuum of cardiac output. Those with the highest cardiac output in the upper blood pressure quintile had the greatest left ventricular wall mass.
Schieken et al. (Sun,) conducted a observational in High blood pressure (n=264). Systolic blood pressure in the highest quintile vs. Systolic blood pressure in the lowest or middle quintile was evaluated on Left ventricular wall mass corrected for body size. School children with systolic blood pressure in the upper quintile had significantly greater body size-corrected left ventricular wall mass compared to those in lower blood pressure quintiles.
